العربية DIN 6914 structural bolts wholesale supplier
XZ Fastener supplies DIN 6914 structural bolts for wholesale buyers serving steel construction, bridge, industrial frame, and heavy equipment projects. These high-strength bolts are commonly ordered with DIN 6915 nuts and DIN 6916 washers, so the full assembly should be confirmed before quotation. Wholesale supply focuses on repeatable dimensions, stable lot marking, practical packing, and documents that match the project specification. Buyers should provide size list, strength requirement, coating, quantity, nut and washer requirement, packing method, and inspection records before production or shipment planning.

Quick Specs
What Buyers Should Know Before Sourcing DIN 6914 Structural Bolts
DIN 6914 structural bolts are high-strength fasteners for steel connections. They should not be purchased like ordinary metric hex bolts. In most project orders, the nut, washer, coating, marking, and inspection documents are part of the acceptance requirement.
Wholesale buyers often supply several projects or distributors at once, so the standard must be clear. Some specifications still call for DIN 6914, while others require EN 14399 assemblies. Confirm the governing standard with the drawing and review the DIN and ISO fastener standards guide before releasing the order.
Common Purchasing Descriptions
Wholesale procurement lists may include structural bolts and general metric bolt items in the same file. XZ Fastener can review DIN 6914 lines together with descriptions such as DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts.
| Purchasing Description | Wholesale Supply Checkpoint |
|---|---|
| DIN 6914 M20 x 80 structural bolts Class 10.9 plain | Confirm standard, head dimensions, property class, head marking, and test report |
| DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers | Confirm complete assembly, set packing, coating match, and lot traceability |
| Hot dip galvanized DIN 6914 structural bolt assemblies | Confirm coating thickness, nut clearance, thread engagement, and project acceptance rule |
| DIN 6914 structural bolts wholesale pallet supply | Confirm carton quantity, pallet layout, labels, gross weight, and inspection documents |
Detailed Specifications Table
| Specification Item | Typical Requirement | Buyer Checkpoint |
|---|---|---|
| Standard | DIN 6914 | Confirm whether DIN 6914, EN 14399, or project-specific equivalent is required |
| Assembly | Commonly paired with DIN 6915 nuts and DIN 6916 washers | Confirm bolt-only supply or complete bolting set before quotation |
| Strength | High-strength structural bolting, commonly Class 10.9 where specified | Confirm mechanical testing, head marking, and certificate format |
| Material | Carbon steel or alloy steel according to mechanical property requirement | Confirm heat treatment route, heat number, and material certificate requirement |
| Finish | Plain, oiled, black, hot dip galvanized, zinc flake, or project coating | Confirm coating effect on thread fit, nut clearance, and tightening behavior |
| Inspection | Dimensional checks, hardness, tensile, proof load, thread fit, coating inspection | Confirm sampling rule, test frequency, and third-party inspection if required |
| Wholesale Packing | Bulk cartons, assembly set boxes, wooden cases, or pallets | Confirm part number, lot number, size, quantity, gross weight, and pallet marks |
Material and Grade Explanation
DIN 6914 structural bolts are selected for load-bearing steel connections. Material quality, heat treatment, hardness, tensile performance, and head marking must be controlled because these bolts are not decorative or low-load hardware.
Class 10.9 is commonly specified for structural bolting where the project allows it. However, the bolt grade alone does not complete the requirement. Nuts and washers must match the specified system, and installation rules may require preload records or site tightening verification.
Surface Finish Selection Guide
| Finish | Wholesale Use Consideration |
|---|---|
| Plain or Oiled | Controlled storage or projects requiring later treatment |
| Black Finish | General protection for controlled environments, subject to project approval |
| Hot Dip Galvanized | Outdoor steelwork where thicker corrosion protection is required |
| Zinc Flake | Corrosion protection with controlled coating build and thread-fit management |
For coating-sensitive assemblies, compare XZ Fastener coated fasteners before confirming production.
Manufacturing and Quality Control
Wholesale structural bolt supply needs repeatability across lots. A correct first batch is not enough if the next batch changes marking, coating, packing, or nut fit. XZ Fastener treats DIN 6914 orders as project hardware with controlled traceability.
- Review project drawings, DIN 6914 requirement, nut and washer standards, and finish requirement.
- Confirm raw material, heat number, heat treatment, and mechanical property targets.
- Control forming, thread rolling, head dimensions, shank length, and thread length during production.
- Inspect dimensions, head marking, hardness, tensile performance, proof load, and thread fit.
- Check coating appearance, coating thickness, and nut assembly after surface treatment.
- Pack by size, lot, assembly set, carton quantity, pallet mark, and document package.
For special lengths, non-standard markings, or project-specific packing, XZ Fastener can discuss custom fasteners according to order requirement.
Applications
DIN 6914 structural bolts are used where steel members require high-strength bolting assemblies. Selection should follow the approved engineering specification and installation method.
- Steel buildings and warehouse frame connections
- Bridge steelwork and infrastructure joints
- Industrial platforms, towers, and equipment supports
- Power plant, mining, and petrochemical steel structures
- Heavy machinery frames where structural bolting is specified
Complete assemblies may require compatible industrial nuts and flat washers to match the project specification.
How to Get a Faster Quotation
Structural bolt wholesale quotations are faster when the request includes the full assembly and document requirement. If the project needs bolts, nuts, washers, coating, labels, and inspection records, list them together in one size table.
| Information Needed | Example |
|---|---|
| Size List | M20 x 80, M22 x 90, M24 x 100 according to project list |
| Assembly Requirement | DIN 6914 bolts with DIN 6915 nuts and DIN 6916 washers |
| Strength and Material | High-strength structural bolting, Class 10.9 where specified |
| Finish | Plain, black, hot dip galvanized, zinc flake, or project coating |
| Quantity | Pieces per size, assembly sets, batch shipment, or project total |
| Packaging and Inspection | Set packing, pallet marks, material certificate, dimensional report, mechanical test report |

FAQ
What are DIN 6914 structural bolts used for?
DIN 6914 structural bolts are used for high-strength steel connections in buildings, bridges, industrial frames, platforms, and heavy structural projects where the specification requires this bolting system.
Can DIN 6914 structural bolts be supplied with nuts and washers?
Yes. They can be supplied as bolt-only items or as assemblies with DIN 6915 nuts and DIN 6916 washers. Buyers should confirm whether the project requires complete sets.
Can DIN 6914 structural bolts be hot dip galvanized?
Hot dip galvanized finish can be supplied when specified. The matching nut clearance, coating thickness, thread fit, and assembly acceptance should be confirmed before production.
Is DIN 6914 the same as EN 14399?
No. Some projects may reference older DIN standards, while others require EN 14399 assemblies. Buyers should confirm the governing standard in the drawing or project specification before ordering.
What inspection records should wholesale buyers request?
Common records include material certificate, dimensional inspection report, hardness test, tensile or proof load test, thread fit check, coating report when required, and packing list by lot.
What information is needed for a DIN 6914 wholesale quotation?
Send the size list, strength requirement, finish, quantity, nut and washer requirement, packaging method, inspection documents, and any project-specific standard or drawing.
